Can't make filesystem

dext · 2012-03-22 00:49:25

SSD is new and ok. I can perform hdparm -Tt, dd, etc.

I can't create and mount partition (tryed ext4, reiserfs). mkfs says everything went ok, but:
- mount -t ext4 says "can't find ext4 filesystem"
- fsck says "invalid superblock"

I'm trying to install Arch. /arch/setup fails on "Prepare Hard Drive", so now I'm trying to create partitions manually, so I better see what is going on. Nothing fancy:

mkfs.ext4 /dev/sda1
mount -t ext4 /dev/sda1 /mnt

PS. I installed Arch without problems and booted it, but then I realize, that I installed i686... I got dual architecture iso to do it again, and now I have this problem.

Long shot, but try to overwrite everything on the disk with zeroes, reboot, and then install x86_64

dd if=/dev/zero of=/dev/your-SSD-disk

Make sure you select your SSD in the above command, and make sure anything you want saved from it is backed up. I'm assuming you don't since it's new though.

I hove done it right after o post this topic. Now i can't write partition table. Fdisk says everything went ok, but fdisk -l shows there is no partition table...

Could you share the exact fdisk command you issued?

I'm sure it went ok, you just need to re-read the partition table:

/sbin/blockdev --rereadpt /dev/your-SSD-disk

edit: or reboot!

That helped - I'm surprised, that reboot didin't.

But recreating partition table doesn't change anything. I still can't create and mount filesystem.

I'm not sure why that happens then, sorry.

If making filesystems works with i686, then it should work with x86_64 too.

- Search for something like "your-SSD-disk linux 64" and see if you find anything
- Your .iso could be corrupted
- mkfs.ext4 when booted in i686 liveCD, then reboot and continue with x86_64 install.

Or you could use GParted Live or Parted Magic to create the filesystem. I always keep PM around on a USB stick in case I ever need to chroot or fix some configuration file.

Corrupted iso... Happened while copying to pendrive.

Installed, but can't boot... Every partition is corrupt after reboot. "Bad magic number in super-block while trying to open /dev/sda1"

First let's google: "Bad magic number in super-block" :

http://www.google.com/search?q=Bad+magi … uper-block

Now, let's click on a possibly related article: HOWTO: Repair a broken Ext4 Superblock in Ubuntu.

Try it.

PS: In my experience, filesystem corruption does not EVER occur, especially if it was freshly formatted (and assuming that the drive is healthy). Maybe you did something to it while it was mounted... Fdisk usually warns you before you're about to do something stupid and asks you if you REALLY want to continue. Maybe you typed "y" instead of "n".
